D4N-612H

The D4N-612H snap action switch is a type of limit switch that helps to accurately control electrical circuits. It is part of the Omron brand of industrial control switches, making it a reliable and long-lasting option for a variety of applications. It is designed to be compact, having a width of just 12mm. Despite its small size, it is rated to be able to switch up to 10A@125V AC and 6A@250V AC, which makes it suitable for a wide range of electrical control needs.

The D4N-612H has a SPDT, closed-circuit contact configuration. This is the type of switch setup most commonly used with limit switches as it is able to control a circuit based on mechanical action. Instead of relying on an electric current to trigger the switch, the switch operates due to the contact being physically closed or opened. This means that the switch is much more reliable as it does not require electrical power to operate.

The D4N-612H has a wide range of applications, including controlling machinery movement, initiating certain processes, and monitoring a variety of equipment and systems. It is designed to be resistant to vibration, meaning it can be used in a wide range of industrial, commercial, and manufacturing settings. Other common applications include control systems, automated doors and windows, water treatment equipment, and security systems.

The working principle behind the D4N-612H is simple - it is a mechanical device that activates or de-activates an electrical switch. The switch is armed with a movable contact arm, which can move when it comes into contact with an object. When the switch is inactive, the contact arm is held open by a spring. When the contact arm is engaged by an object, it causes the arm to close and the switch to activate, closing the circuit and switching on the power.

When the contact arm is no longer being engaged, the spring reopens the contact arm and the circuit is broken. This cycles of engagement and disengagement is the driving principle behind limit switches such as the D4N-612H. This enables it to accurately control electrical circuits and to provide reliable, long-lasting performance.

The D4N-612H snap action switch is a reliable and versatile industrial limit switch that is designed to provide reliable performance and accurate control of electrical circuits. Its SPDT contact configuration and vibration-resistant design make it suitable for a wide range of applications, including control systems, automated doors and windows, water treatment equipment, and security systems. Overall, it is a great option for those looking for an accurate, reliable, and long-lasting limit switch.
